BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 651,183, datedJune 5, 1900.

Application filed October 27, 1899. Serial No. 734,906- (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS L. COOK, a citizen of the United States of America, and a resident of Springfield,in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a full, clear, and exact description.

This invention relates to improvements in stoppers for bottles, the object being to provide a stopper composed of wood, and therefore very cheap and inexpensive, but so conplug portion of the stopper, having therestructed as to have a sufficient flexibility to enable it to conform to the opening in the neck of the bottle to fill the same while in compression or exerting a yielding force relatively thereto.

The stopper is more especially designed for closing bottles having comparatively-large necks and mouths-such as those used for containing dentifrice and other powders, chemicals, or materialsso that by the removal of a supplemental stopper-cap the contents or portions thereof may be removed from the bottle Without the removal of the plug or stopper proper.

The invention consists in a stopper for a bottle having the plug portion thereof formed annular with an intervening annular chamber and having the central member thereof constructed tubular and extended upwardly, the cap for closing the upwardly-extended end of said tubular part, and a portion for covering the top of the annular chamber within the stopper-plug.

In the drawing, A represents the body or within the opening or chamber a.

The plug portion A of the stopper is formed with a central opening, surrounding which is the annular upstanding portion 7c, which is preferably projected above the top of the plug portion, this upwardly-extended part being surrounded by the centrally circularly apertured stopper top m, which is fitted about the part 70 and has a concentric shoulder portion m fitting between the external and internal walls of the said plug portion, between which external and internal portions is the annular space a, which imparts the resiliency or flexibility to the stopper-plug. The web I) unites the outer annular wall to the inner tubular part 7.5. The cap a is removably fitted on the upwardly-protruding central tubular part 70.

The said stopper is advantageous for employment in bottles having comparativelylarge neck openings and such as are employed for containing powders or pulverized or granulated material, such as dentifrice. The parts a and on maybe integrally formed, if desired, and the shoulder portion may be so constructed that in entering the downwardly-convergent annular space which is upwardly opening within the plug portion of the stopper it will exert a crowding action to expand the outer wall, and thereby render it tighter in its fit within the bottle-neck.

The stopper may be made by turning from solid wood or by reducing the wood to a pulp and producing thestopper by molding.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A stopper for a bottle having the plug portion thereof formed annular with an intervening annular chamber, and having the central member thereof constructed tubular and extended upwardly, the cap for closing the upwardly-extended end of said tubular part, and a portion for covering the top of the annular chamber within the stopper-plug.

Signed by me at Springfield, Massachusetts, this 25th day of October, 1899.
